Actually ioctl() should be used, but I see the point. Updating
a counter in VIRTUALDEVICE is much less hassle then trying
to retrieve the number of bytes in a NETBUF queue or whatever.

When changing the structure, what about adding both sizes,
input and output buffer?

What about the type? IMHO, size_t should be sufficient. Or does
anybody see the need for an unsigned long?

Again my previous post was unnecessary. Yes, to CVS HEAD please. :-)
